不同水稻品种主要生育期冠层光谱特征分析
Canopy Spectral Characteristics of Different Varieties of Rice during Main Growth Stages
摘要
Abstract
Based on the two indica rice varieties and two japonica varieties, the difference of canopy spectral reflectance between dif-ferent rice in major growth period,and the variation trend of canopy spectral reflectance of different varieties at different growth stages were analyzed.The results showed that the differences of canopy spectral reflectance in 350~750 nm band was very small,but the dif-ferences of canopy spectral reflectance were gradually decreased with the advance of the growth process in 750~1300 nm band. There had obvious difference of canopy spectral reflectance of each variety at the same growth stage, and also had obvious difference of canopy spectral reflectance of the same variety at different growth stages. Therefore, the effects of different varieties and different growth stages should be considered in the hyperspectral study of rice.关键词
